Showing the second form exactly in place of the first form

Question

From the main form (Form1) I call to show another form (Form2). but I want it to show exactly the same place and size as form1, so that we can no longer see form1 until we close form2 or move it somewhere else. so I wrote the following lines:

        Form2 f2 = new Form2();
        f2.Left = this.Left;
        f2.Top = this.Top;
        f2.Size = this.Size;
        f2.Show();

But he still has problems. form2 we are not completely on form1. any other thing i should add to the code?

You can still move form2, as I just mentioned about the form, but this was not indicated as part of this question.
